SPC MESOSCALE DISCUSSION 0644 FOR CENTRAL/ECENTRAL TX
   CONCERNING...SEVERE THUNDERSTORM WATCH 219...
   
   VALID 031253Z - 031500Z
   
   CLUSTER OF STORMS WILL CONTINUE TO POSE AN ISOLATED LARGE HAIL
   THREAT OVER THE NEXT FEW HOURS ACROSS CENTRAL/ECENTRAL TX. 
   
   LOW LEVEL CONVERGENCE IN THE VICINITY OF THE 850 MB FRONT CONTINUES
   TO MAINTAIN CONVECTION ACROSS CENTRAL TX. RECENT TRENDS IN THE
   REGIONAL VWP/PROFILER DATA SUGGESTS THAT CONVERGENCE HAS BEEN
   SLOWLY WEAKENING AS LOW LEVEL JET CONTINUES TO VEER OVER
   CENTRAL/ERN TX. ALTHOUGH THE 12Z FWD SOUNDING WAS UNAVAILABLE...THE
   12Z SHV SOUNDING INDICATED A MODERATELY UNSTABLE AIRMASS /2700
   MUCAPE/ WITH SOME INHIBITION NOTED IN THE 700 MB LAYER. DUE TO THE
   EXPECTED CONTINUED DECREASING CONVERGENCE/VEERED LOW LEVEL
   INFLOW...ONGOING CONVECTION SHOULD CONTINUE TO WEAKEN
   SLOWLY...WHILE POSING AN ISOLATED SEVERE THREAT THROUGH 03/15Z.
